I've been hearing a lot about trainer jets lately...some people just don't like "twin boom" jets...so here are some alternatives:

EXM Sport Jet, all wood construction, built like a modern 3D plane and it can the stress of high Gs. Nice thing about this one is that a smaller turbine can be used since it is light for its size.

Shulman Aviation Turbinator, all wood construction with purpose made gear mounts that are a little stronger for grass and the occasional harder landing. Also can use a wide range of turbine sizes.

Futura, all composite sport jet with light wing loading. This plane flies like a pattern ship and is has a large frontal area on purpose to take advantage of the drag to keep a constant speed during aerobatics.

All these jets slow to a walk for landing and can be flown with 1/4 throttle on final with the flaps down to minimize spool up time for a go around. Even more drag can be generated with the use of "crow" (up ailerons) if a higher power setting is desired on final and into the flare.
